Comparing Ratios and Juice Concentrates

This lesson focuses on comparing ratios using ratio tables. It covers creating equivalent ratios by scaling up and down, understanding relationships in ratio tables, and comparing texting rates to determine the fastest texter. Additionally, it explores comparing juice concentrate ratios. The lesson concludes with activities on Socrative and Khan Academy.

What does it mean to scale up a ratio?

• To subtract a constant from both terms of the ratio

• To add a constant to both terms of the ratio

• To multiply both terms of the ratio by the same number

• To divide both terms of the ratio by the same number

If you have a ratio of 30:80, what is one way to scale it down?

• Add 10 to both terms

• Subtract 10 from both terms

• Divide both terms by 5

• Multiply both terms by 2

In a ratio table, what does a simplified ratio represent?

• The average of all values in the table

• The total sum of all values

• The relationship between two quantities in their simplest form

• The difference between the largest and smallest values

Why can't you simply choose the texter with the most words as the fastest?

• Because the number of words is not relevant

• Because the time intervals are not the same for all texters

• Because the words are not spelled correctly

• Because the texters used different devices

How do you determine the fastest texter using ratios?

• By comparing the total number of words typed

• By finding the common time interval and simplifying the ratios

• By comparing the number of errors made

• By checking who typed the longest message

What is the simplified ratio for McKenry's texting speed?

• 1:55

• 1:45

• 1:50

• 1:40

How can you compare juice concentrates effectively?

• By tasting each juice

• By finding a common amount of water and comparing the juice added

• By checking the price of each juice

• By comparing the color of the juices

Which juice has the strongest taste if Laredo's ratio is 3:1?

• Franka's juice

• All have the same taste

• Milton's juice

• Laredo's juice

What is the importance of finding a common amount of water in juice comparisons?

• It makes the juice look more appealing

• It ensures the juice is safe to drink

• It allows for a fair comparison of juice strength

• It helps in determining the price of the juice

If Franka's juice has a ratio of 5:2, what does this mean?

• For every 5 parts of water, there are 2 parts of juice

• For every 5 parts of juice, there are 2 parts of water

• For every 5 parts of water, there are 2 parts of sugar

• For every 5 parts of sugar, there are 2 parts of water
